MACHINE FOR SEPARATING FIBERS FROM THE PULP AND OTHER EXTRANEOUS MATTER OF PLANTS AND TREES.

Speecation of Letters Patent.

Patented oct. 15, 1907.

Application filed April 17, 1906. Serial No. 312,169.

To all Iwhom it may 'concern' Be it known that I, EUGENE BEHRENDT, a citizen of the United States, residing in Manila, Philippine Islands, have invented a new and Improved Machine for Separating Fibers from the Iulp and other Extraneous Matter of Plants and Trees, of which the following is a full, clear, and exact description.

The invention relates to machines for separating fibers from the pulp and other extraneous matter of plants and trees, such as shown and described in the application for Letters Patent of the United States, No. 296,498, filed by me January 17, 1906.

The object of the present invention is to provide certain new and useful improvements in the machine above referred to whereby a single draw head only is required for a continuous operation of the machine, the construction and operation of the draw head and its carrier being exceedingly simplified.

The invention consists of novel features and parts and combinations of the same which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure I is a side elevation of the improvement, Fig. 2 is a plan view of one side of the machine, parts being omitted and parts being in section, Fig. 3 is an enlarged cross section showing the driving shaft for the endless carrier and the clutch mechanism for throwing the driving shaft in or out of gear; Fig. 4 is a cross section of the improvement on the line 4 4 of Fig. l; Fig. 5 is an enlarged cross section of the drawing mechanism, the section being on the line 5-5 of Fig. l; Fig. 6 is a sectional side elevation of the same on the line G-G of Fig. 5; Fig. 7 is an enlarged cross section of the draw` head in a closed position; Fig. S is a sectional side elevation of the same on the line 8-8 of Fig. 7 and Fig. 9 is a like view of the same in an open position.

The reduced end A of the material A to be treated is clamped between the jaws B B2 of a draw head B, adapted to be moved lengthwise of the machine in the direction of the arrows a for initially drawing the material A successively through a stripping device O, a combing device D, a second stripping device E, and a cleaning and polishing device F, to finally bring the fibers to a drawing mechanism G for relieving the draw head B of its drawing function and for engaging the fibers with a view to draw the material through the several devices C, D, E and Fl The several devices mentioned are mounted on a suitably constructed frame H, and are preferably of the construction more fully shown and described in the application above referred to, so that further description of the same is not deemed necessary.

The drawing mechanism G is actuated from a main driving shaft I extending transversely and journaled in suitable bearings carried by the frame H. On the driving shaft I is secured a pulley I connected by a belt I2 with other machinery for imparting a rotary motion to the said driving shaft I. On the latter is secured a pinion I3 in mesh with a gear wheel I*1 motilited loosely on a shaft J journaled on the rear portion of the main frame H, and on this shaft J are secured' sprocket wheels J connected by sprocket chains J2, and with sprocket wheels J 3 secured on a transverse shaft J 4 journaled in bearings J5 held lengthwise adjustable on the front end of the main frame II, so as to give the desired tension to the sprocket chains J 2. A pair of oppositely disposed links of the sprocket chains J2 are pivotally connected at J G (see Figs. 7, 8 and 9), with the clamping jaw B of the draw head B, so that when the machine is in motion and the sprocket'chains J2 travel in the direction of the arrrows a, then the draw head B is bodily carried along by the said chains J 2 in the direction mentioned.

The jaw B of the draw head B is fixed to the chains J 2, and the jaw B2 is movable relative to the fixed jaw B to allow of opening and closing the jaws, with a view to close the jaws to clamp the end A of the material in position and for opening the jaws for removing the end A after the fibers are cut off, as hereinafter more fully explained. For the purpose mentioned, the movable jaw B2 is provided at its ends with upwardly extending lugs B3 in which is journaled a shaft BA1 provided at its ends with eccentric trunnions B5 journaled in lugs B6 secured to or formed on the fixed jaw B. Now by turning the shaft B4, the jaw B2 is moved toward or from the xed jaw B according to the direction in which the shaft B4 is turned. In order to properly guide the jaw B2 toward and from the fixedjaw B the lugs B are provided with guide lugs B7 projecting into guideways B8 formed in the lugs B3, see Figs. 7 and 8. The shaft B4 is provided with an aperture Bg to permit the operator to insert a stick or a handle K for conveniently turning the shaft B, with a view to move the jaw B2 toward or from the fixed jaw B for the purpose above mentioned The fixed jaw B is provided at its ends with trunnions B1", mounted to travel on longitudinally extending guideways H formed on the main frame H, and on the said trunnions BU are journaled friction rollers L for engaging cams L on the several devices O, E and F, for lifting the cross heads thereof to allow the draw head B to pass between the members of the said devices.

The hub of the gear wheel I is provided with a clutch member I5 adapted to be engaged by a clutch member N, mounted to slide on and to turn-with the shaft J, and the said clutch member N is engaged by a shifting lever O, fulcrumed at O on the main frame H (see Fig. 2), and the forward end of this shifting lever O is in the form of a pin O2 projecting into an angular slot P (see Fig. 4), formed in a vertically disposed cam P, mounted to slide up and down in guideways Q and Q/ at tached to or forming part of the main frame H. On the upper end of the cam P is arranged a wedge-shaped offset P2, adapted to be engaged by one of the trunnions B10, so that when the draw head B has passed around the sprocket wheels J 2, it finally acts on the offset P2 to lift the latter and its cam P, so that the pin O2 is moved inwardly whereby a swinging motion is given to the shifting lever O to throw the clutch member N out of engagement with the clutch member I5, When this takes place7 the rotary motion transmitted by the gear wheelI4 and the engaged clutch members I5 and N to the shaft J, is stopped, so that the traveling motion of the chains J2 and that of the draw head B ceases.

' The draw head B thus comes to a stop at the front of the machine to allow the operator to open the jaws BC B2 for removal of the reduced end A/ of the material A previously drawn through the machine, and to allow of inserting the reduced end Al of a batch of material to be treated subsequently. When this has been done and the jaws B, B2 have been closed, then the operator presses the cam P downward by hand, so that the shifting lever' O is actuated to move the clutch member N back into engagement with the clutch member I5 to rotate the shaft J and thereby start the sprocket chains J2 for the latter to move the draw head B bodily through the machine. In order to hold the cam P in either of its two positions mentioned, the lower end of the Cam is provided with a spring tongue P3 (see Fig. 4), having spaced teeth P4, P5 adapted to engage a recess in the bearing Q2.

The main drawing device G consists essentially of rubber covered rollers G/, G2 (see Figs. 5 and G), arranged one alongside the other and operating in conjunction with a pressing roller G3 adapted to press the fibers in contact with the upper peripheral surfaces of the rollers Gf, G2, all. as more fully described in the application above referred to, it being understood that the rollers G/, G2 are driven from the main shaft I, and the roller G3 is capable of being lifted bodily by the action of the friction rollers L to allow the passage of the draw head B between the rollers G G2 and G3. In order to keep the rollers G, G2 and G3 clean at all times, suitable brushes R, R/ and R2 engage the peripheral faces of the said rollers, the brushes R, Rf being fixed to the main frame I'I and the brush R2 being fixed to the cam links R3 in which the roller G2 is journaled.

The operation is as follows: When the main shaft I is rotated, then the rollers G, G2 are driven and a traveling motion is given to the carrier chains J2 as long as the clutch members I5 and N are in mesh, that is, until the draw head B is between the cam P and the first stripping device C. The shaft J, the sprocket chains J2 and the draw head B are now at rest to allow the operator to open the jaws B B2 of the draw head B to permit the insertion of the reduced end A/ of the material A, the operator then closing the jaws Bf, B2 to clamp the end A in place in the draw head. The operator now presses the cam P downward to start the draw head B on its forward journey and to carry the material A along. The draw head B in its forward travel passes between the members of the cleaning devices C, D, E and F and between the rollers G, G2 and G3 of tnhe drawing mechanism G, so that the material is drawn forward through the` several devices C, D, E and F for the purpose of completely separating .the extraneous material from the fibers and to thoroughly clean and polish the same. After the draw head B has passed the drawing mechanism G, the operator at the rear end of the machine with a knife cuts the fibers adjacentv to the jaws Bf, B2 to allow the draw head to travel on and return to starting position with the reduced end A/ still clamped between the jaws Bf, B2. In the meantime, the main drawing device G draws the fibers onward, the forward ends of the fibers being grasped by the operator at the rear end of the machine for conducting the fibers from the machine. l When the draw head B passes up over the sprocket wheels J3, one of its trunnions Bm acts on the cam P to throw the clutch member N out of engagement with the clutch member I, so that the shaft J, the sprocket chains J2 and the draw head B come to a standstill. The operator at the front of the machine now opens the jaws B/, 2, removes the reduced end A/ and clamps the reduced end A/ of a batch of new material in place between the jaws BC B2, after which the operator presses the cam P downward and the above described operation is repeated.

By the arrangement described, it is but necessary to employ an unskilled operator at the front end of the machine and an unskilled operator at the rear end of thc machine, as the performances required of such operators are exceedingly simple and require no skill.
